- on ar724x, rx buffers can be aligned with an offset of 2, which keeps the ip header aligned
- alignment offset is only added if the ar8216 workaround is not active and the phy driver does not advertise its own packet alignment
- ar71xx and ar91xx can not handle rx alignment offsets, however taking a hit on unaligned exceptions seems to have less overhead than re-aligning the data for large packets
- use memmove to re-align small packets, if necessary
tested on ar9132, ar7240 and ar7242 based devices without ar8216 headers

Swconfig needs to make sure that requested vlans/ports actually exist,
else it might read or modify memory not belonging to itself.
This patch adds a quick range check in swconfig's kernel part to
prevent accidential or intentional memory modification.

This patch brings up the net5501 platform.
Note that the x86/ target included support for all x86/ class
processors. That's not technically correct. This should be constrained
only to the "generic" subtarget. Every x86-class target that isn't
generic should be able to select only the optimizations/capabilities
applicable to that architectural variant.
It's also assumed that all x86 processors have keyboard & mouse ports,
ISA, DMI, ACPI... the embedded ones typically don't. Again, moving
that to the generic subtarget.
Fortunately, this was a fairly benign tweak.
The net5501 board includes the following logic:
Geode/LX processor
CS5535 super-I/O chip
PC87360 sensor chip
Via Rhine Ethernet controllers
Via Sata controllers
USB, LEDS, I2C

This patch is rather a cosmetic patch. It fixes the following issues:
* Demote the unknown device message to debug level to not spam
the log.
* Fix the version print of the unknown device message.
* Output the 'attach' message only when attaching as switch driver,
not when attaching as phy driver.
* Correctly return NET_RX_DROP when dropping packets.

Ag71xx needs to call the phy's netif_receive_skb() to allow phy drivers
to mangle rx packets. This patch fixes it.
This fixes the header mangling of the AR8216 driver.
